Application filed March 11 Z '0 (1. 25 in]: our 1 1mm concern Be it known that I, Torin V. Ciznii, a citizen of the United States, residing at Clutieryin the county of Tania and State of Iowa, have invented certain new and useful iinprctenients in Portable Elevators, of which the follmving is a specification.

This invention rel tee to farm ole-raters used in conveying grain, cribbing corn, and the like and embraces certain inigrm'ements in the construction of such elevators, the object of which is to render them more easily portable and to increase their general ethciency will be more fully set out hereafter.

The invention is clearly disclosed in the description and claim following. reference being had to the accompanying drawings, in Which Figure 1 is a general View in perspective of an elevator embodying my improvements. Fig. is a fragmentary longitudinal section of the main conveyor,showing a reinotable rid set. in the bottom of the upper deck and cischarge spout below it for shelled corn in through the grid. Fig. 3 isa View e grid in perspective. .1 he elevator proper is mounted on a snoportnig i'ranie provided with suitable carry ing wheels A, described in a divisional copending application lie. TSLIOQ, filed April 1% 1913.

B B are two longitiuliual bars connectingv the front CiCFfb C; and the rcar,aXlebars l). The connection at the rear is direct, us will he soon. being fastened between the axle'bars. it the front end, however. the reach-liars .i connect with yokcs E, which serve as guides for the main driving shaft 1*. Th Yokes secured rigit hy to the i bar. and thus form parts of the rigid n'iam frame on which the ole ator is mounted. To the front cross-bar pirotally attached the axle G, which is pro H to receive the front carrying Wheels.

The c *or is of theendless apron pe, and con'iprises an adjustable receiving porticn the forward end of the machine. and a discharging body extending over the runcorn from the cob. It is not desirable to i through. but are narrox crib this sheilei corn, as it is apt to gather in more or less compact masses in the crib and there heat an mold. i ccordingly provision is madet'or riddling out. the shelled corn it passes up to v conveyer. The construction is clearly e shown in Figs. 2 and 3.

The elevator K is provided with an upper and lower deck, K and K respectively, the conveyor K running over the ppel' deck in the usual Way. in the upper deck is provided a considerable opening and in this is titted removable grid Ki thev slots in which-permit t e shelled corn to pass v enough to carry. the cars of-corn. Across a gap the lower deck fixed an i-- lined spout K to carry the "helled corn out of the conveyer.

It- Will he seen-that the main elevator is hinged at K, so that the rear section may be folded back OYGF the mid-section for convenience in transportation. i

The elevator is suspended by means of a stirrup K", provided with a suitable sheave K from a derricl: L pivoted at- L to. the rear axle. it; one side of the derrick is a winch if, reterahly provided with a wormgear and hand-lover as shown. Around the drum of the which runs a cable L A assing thence over a sheave'L-, thence under the.

stirrup sheave hi and up to a connection *ith the opposite side of the derrick near the top. T ie elevator may thus be easily IiOlSted to any desired elcvation. When completcl v depressed it rests on the rear axle and the derrick ma then be folded forward in the same manner as the rear section of the elevator.

it the front endthe inid-seation of the elevator is provided with suitable bearings Ill. both to report the front or hopner section of the elevator, and also for the driving therefor. Sn one of these hearings aily mounted la hearing bracket I? "hinted to take a horizontal shaft for L bevel-gear O. and a short shaft perpen dicular thereto, for a pinion O .cjhdahly connected with this bracket 1s another bracket Nhsiinilarly adapted to take a short- ;Ft for a pinion O and the main driving shaft i already referred to. The shinshafts for the pinions are made .to telescope tosni-tl'ier. one of them being preferably square, as shown. The brackets may thus be moved in or out with respect to each other for any desired adjustment. A hub of the lower bracket .project. into the slot in the yoke E, and by means of cables P pass ing over suitable sheaves P and attached to a Winch P the Whole forward end of the elevator may be raised or depressed at will.

The forward section of the elevator, is provided with hinged side-boards Q which may be tilted downwardly, as is shown in the case of the nearer. one, for convenience in shoveling in material. This section tilts in a circle concentric with the shaft which drives its con. er. Suspension leverage is provided in standing bars Q? and Q connected by t e rods Q. To the inner pair is attached a pair of cables R, connecting at their other ends With a Winch S.- The elevator section may thus be set With its forward end near the ground, or at any desired elevation above it, and'when not in use it may be folded back over the mid-section for convenience in-moving from place to place.

Having thusdescribed my invention, what is clairfied is: I

In an elevator, the combination of a supporting frame, the 'frame having slotted yokes near the front end for the driving shaft to pass through, adischarging conveye'r mounted over said frame pivotally at its forward end, bearings for the driving shaft attached thereto, a shaft mounted therein and passing through the yokes, a bevel gear thereon, a receiving conveyer piv otally 'attachedto the dischargingconveyer at its forward end, a driving'shaft therefor provided with a bevel gear, a telescoping cross-shaft with pinions thereon meshing with said bevel-gears, respectively, and brackets for said shafts attached slidably together, whereby the distance between the driving shafts may be varied, as speci- In testimony vhercof I affix my signature in presence of two Witnesses.
